Mayo Clinic enrolls first patient for ExThera Medical’s PURIFY-RCT II trial

MARTINEZ, Calif. – ExThera Medical Corporation’s PURIFY-RCT II trial to evaluate the efficacy of pathogen removal from severely ill patients suffering from pathogen shock is moving forward with the first patient enrollment at Mayo Clinic.  This comes after ExThera Medical completed the first phase of the prospective interventional multicenter PURIFY-RCT trial, where pharmacokinetic/ pharmacodynamic safety was demonstrated.  This means the Seraph 100 blood filter treatment does not reduce bloodstream concentrations of tested anti-infective medications that are currently used as a critical frontline/standard of care treatment against bloodstream infections.

“Having successfully completed the PK/PD phase of the PURIFY-RCT trial, we are excited to begin enrolling patients to further demonstrate efficacy of Seraph 100 in the treatment of pathogen-induced septic shock,” said Erin Borger, CEO of ExThera Medical. “Enrolling the first patient in this phase of the trial is a crucial milestone toward commercial availability and growth in this therapy space.”

The Seraph 100 enables infection source control through rapid extracorporeal blood filtration of pathogens and has been granted multiple Breakthrough Device Designations for patients suffering from life-threatening bloodstream infections, having been deemed a “First-In-Class” medical device by the U.S. FDA.

“Reducing pathogens from blood stream infection patients in the ICU addresses a tremendous unmet need,” said Mink Chawla, M.D., and Chief Medical Officer of ExThera Medical. “We are excited about the prospects of this study, and if successful, this investigational treatment can be used for patients where anti-infective drugs are inadequate or to combat the next pandemic.”

The PURIFY-RCT trial is sponsored by the Department of Defense in collaboration with the Henry M. Jackson Foundation and the Uniformed Services University of Health Sciences to evaluate the safety and efficacy of the Seraph® 100 Microbind® Affinity Blood Filter. The clinical trial will be conducted in centers across the United States, targeting improvements in both clinical outcome and health economic endpoints.

About Seraph 100 and the ONCOBind Procedure
As a patient’s blood flows through the Seraph 100 filter, it passes through a bed of small beads with receptors that mimic the receptors on human cells that pathogens target when they invade the body. Many harmful substances are quickly captured and adsorbed onto the surface of the beads and are thereby subtracted from the bloodstream. Seraph adds nothing to the bloodstream. It targets the pathogens that cause the infection, while it also binds and removes harmful substances generated by the pathogen and by the body’s response to the infection. Seraph’s proprietary adsorption media (the beads) constitute a flexible platform that uses immobilized (chemically bonded) heparin for its well-established blood compatibility and its unique ability to bind circulating tumor cells, bacteria, viruses, fungi, and important sepsis mediators reported to contribute to organ failure during sepsis.
